Abstract
Radiation transport models of two high purity germanium detectors, GeII and GeIII, located at the University of Alabama have been created in GEANT4 (Agostinelli et al., 2003)[1].These detectors have been used extensively for radioassay measurements of materials used in various low background experiments. The two models have been validated against actual data under several scenarios typically seen in radioassay measurements. The systematic uncertainties of the models for GeII and GeIII are estimated to be ∼12% and ∼9% respectively.
